3. The vector field F below is in the xy-plane and looks the same in all other horizontal planes. In other words, F is independent of z and its z- component is 0. 0 a. Is div(F) positive, negative, or zero at P? Explain using the vectors around point P. b. Determine whether curl(F) is 0 or not. Show your work and/or explain how you know.
